The most common technique used for modeling linear, time-invariant systems is the block diagram, with the mathematical model represented as a transfer function. As an example of the first situation - ...

A recurring problem in feedback control theory is the determination of a system transfer function (as a Laplace transformed function of s), starting from a block diagram of the system. One commonly ...

Block diagrams and signal-flow graphs are used to represent and to obtain the transfer function of interconnected systems. The reduction of signal-flow graphs is considered simpler than the reduction ...
